I have created one project in my Firebase Account. In this project, I have added two android apps.
Now, while sending push notification through Firebase console, I see the option of selecting my individual app as shown below
But, while sending notification through Postman, I don't know how can I send notification to only a particular app?
Should I create two individual project for both my apps, so that the server key is different?
But, I feel there should be a way to send notification without creating multiple projects for multiple apps.
Sending notifications to user segments is not available programatically i.e. not available when using the API.
A workaround you could use is Topics Messaging, creating a topic for the specific app and subscribe the corresponding users.
